The method involves selecting combustion indicators e.g. crank angle position (CA10), and defining a multidimensional space in which each dimension corresponds to one of the indicators and combustion is represented by a point. A closed surface surrounding the points corresponding to normal combustions, which does not surround points corresponding to abnormal combustions is defined in the space. Combustion of a cycle is represented by a point in the space by determining the indicators. A position of the point is determined relative to the surface to deduce an abnormal nature of combustion. The distance between the point and the surface is determined to deduce a severity of the abnormal nature of the combustion. The progress of the abnormal combustion is controlled as a function of the severity of the abnormal nature of the combustion. |
